I'll revive this and chime in with my opinion.
It all depends on what you're using them for. I use either of them 95% of the time for archery and rifle hunting. I have the Vortex Fury HD 5000s and a Leica 2400R. Never had an issue with any of them but I've used the Furys only a handful of times in the field and have since gone back using only the 2400R every time. Here's why:
For archery distances, there is no need for RF binos. My eyes are still good enough that I can see from quite a distance if it's a good buck or not before getting within shooting range to where I would only need a small compact rangefinder to know the exact distance for the shot. Sometimes RF binos can actually be TOO GOOD for these short distances.
Compact Leica RF every time for archery.
For rifle distances, the longest range caliber that I use is 300 win mag. All my scopes are duplex reticles and with properly sighting them in, I can shoot 350 yards before needing to hold-over to compensate for bullet drop and wouldn't trust myself effectively killing any animal with it past 800+/- yards with a VERY clear shot. In most areas I hunt, I would be extremely lucky to get a clear shot on any game past that distance. From my experience, the Leica 2400R can easily handle distances over 1200 yards every single time.
So FOR ME and my needs, the Leica RF every time for rifle hunting.
Smaller, lighter, and does exactly what I need every single time. At a fraction of the cost to RF binos.
Combos certainly have their place, especially with target and/or long range shooting of any kind.
But there isn't any advantage RF binos have over a stand alone RF for my hunting needs.
None of this statement is factual, just my personal opinion from self experiences.
